Abstract

The invention provides a gas supplementing device and method for environment-friendly insulated electrical equipment. The device comprises a C4F7N gas cylinder, a buffer gas cylinder, an inflation gaspipe, ball valves, a one-way electromagnetic valve, a temperature sensor, a pressure sensor, a density sensor, a gas mixing tank and a control processing device, and is an intelligent inflation device for novel environment-friendly gas in application. The problem of the amount of gas required in the gas inflating and supplementing process of the equipment can be solved. The temperature sensor, the pressure sensor and the density sensor are arranged in the gas insulated electrical equipment, the quantity of C4F7N and buffer gas which need to be supplemented is determined according to the temperature, pressure and gas density parameters respectively collected by the three sensors, the corresponding ball valves are opened to complete the gas supplementing operation, remote control can be realized, safe operation is guaranteed, and meanwhile the operation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering gas insulation, and in particular relates to a gas supply device and method for environment-friendly insulating electrical equipment. Background technique [0002] SF 6 Insulation and arc extinguishing media are widely used in power equipment such as gas insulated switchgear (GIS) and gas insulated lines (GIL), but their global warming potential is about CO 2 23,900 times of that, the lifetime in the atmosphere is as long as 3,200 years, which is harmful to the environment. Therefore, seeking a new type of SF 6 Environmentally friendly alternative gases are hot issues in the power industry. [0003] C 4 f 7 The global warming potential of N is about CO 2 2100 times lower than SF 6 Gas, non-toxic, non-corrosive, dielectric constant about SF 6 2 times. Its liquefaction temperature is relatively high, and its liquefaction temperature is about -4.7°C under one atmospheric press...
